Founded in 1897, Chelsea Clock Company is one of the oldest, and largest clock manufacturers in the United States. For over a century, Chelsea’s craftsmen have been designing and meticulously building some of the world’s most exquisite time machines. Today, the company continues to manufacture and repair clocks at its original corporate headquarters in Chelsea, Massachusetts.

The Chelsea Promise
A Chelsea Clock is an exquisite time machine; each one an individual work of art, made by an elite group of master clock makers with the same relentless precision and craft for over 100 years.

Our Nautical Roots
Since the turn of the 19th century, Chelsea Clock has been deeply rooted in a tradition of keeping time at sea. Our nautical clocks have sailed the seas with the U.S. military and graced the ocean’s most impressive yachts.

The Choice of Presidents
1969 – President Johnson watches an Apollo spaceflight from the white house, with his U.S. Navy Chelsea Pilot House Clock resting on his television.

A History of Innovation
Chelsea celebrates a proud history of firsts. Like our military-style Navy deck clocks, first made in the 1940s to withstand the rigors of battle and life at sea. Our Patriot Deck Collection continues to reflect this innovative thinking and craftsmanship.
